I have installed the delivery unit for Graph viewer on a MDC in the HANA trial account. I am not able to view the graph workspaces. When I tried to view the URL for graph viewer, I get Backend error:error. On analysing using the developer tools, I found that the error was http 403 and debugged further to find that the CSRF token which comes from the Get request (for the file csrf.xsjs) is not working for the file graphrequest.xsjs.
I have not done any changes to the standard delivery unit and it is out of the box. I found a thread with the same issue (https://answers.sap.com/questions/73601/graph-viewer-not-working.html) but it is unanswered. Can anyone help?
